Carbon steel necked butt welding flange is a common flange type with a necked design used to connect pipes, valves or equipment to ensure the safety and reliability of the pipeline system. The following is basic information about carbon steel necked butt weld flanges:

Features:

Neck design: This type of flange is characterized by a long neck that is used to be welded to the end of the pipe to provide a reliable connection.

Material: Made of carbon steel, common specifications comply with ASTM A105 standards, suitable for general industrial applications.

Scope of application: Carbon steel neck butt welding flange is suitable for pipeline systems under medium and low pressure and temperature conditions.

Welding performance: The long neck provides more contact area, enhancing the strength and stability of the welded connection.

Standard Sizes: Typically conforming to ANSI/ASME B16.5 standard specifications, available in various diameters and pressure ratings.

Widely used: It is widely used in pipeline connections in petrochemical, papermaking, food processing, water supply systems and other fields.

Advantages：

1.Reliable Connection: Neck welding flange provides a strong connection suitable for general industrial applications.
2.Complies with standard specifications: Usually conforms to international standards, ensuring consistency in size and quality.
3.Wide scope of application: Provides stable and reliable pipeline connections under general medium and low pressure conditions.

Selection of carbon steel necked butt welding flanges:

When selecting a suitable carbon steel necked butt weld flange, you need to consider the pressure level of the piping system, the working environment and the fluid medium. Be sure to choose the correct size, material and specifications to ensure the safe operation of your piping system.

Overall, carbon steel necked butt weld flanges are a common and reliable connecting element suitable for pipe connections in general industrial applications.
